Question

100 gm
Caco3 when heated gives 56 gm
Cao and
44 gm of co2
Prove that the data given is according to
the law of conservation of mass.
​

Answer 1

Answer:

The balanced equation for the reaction is:

CaCO3→CaO+CO2

  10 gm         5.6 gm      4.4 gm

Mass of CaCO3(10 gm)= Mass of CaO (5.6 gm) + Mass of CO2 (4.4 gm)

Hence, it proves the law of conservation of mass.

Answer 2

Answer:

100 grams of calcium carbonate (whether in the form of marble or chalk) are decomposed completely, then 56 grams of calcium oxide and 44 grams of carbon dioxide are obtained'.
